EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN 772-20 testing. This European standard specifies a method for determining the flatness of surfaces of aggregated concrete, engineered stone and natural stone masonry units.
The testing method usually involves measuring the deviation from the flatness of the surface of the wall unit. This is usually done using a straightedge and feeler gauge or other suitable measuring device.
The standard provides guidance on the selection and preparation of masonry units for testing. This includes details of the number of samples, their dimensions and any conditioning requirements.
EN 772-20 outlines the tools and equipment required for the testing process. This includes specifying the dimensions and specifications of the straight edge as well as the use of feeler gauges or other suitable measuring devices.
EN 772-20 may include criteria defining an acceptable level of flatness for masonry units. Meeting these criteria ensures the units are suitable for use in construction projects.
In general, EN 772-20 describes a method for measuring the flatness of masonry units. It involves using tools such as straightedge and feeler gauges to measure any deviation from a perfectly flat surface.
